This is the Signal Private Messenger desktop client, an app that's already on iPhone and Android and guarantees privacy by encrypting our data traffic

For quite some time, privacy in communications has been an important issue that worries many Internet users. If you also are concerned about this matter and you want to talk to your contacts in an anonymous and private manner, you can resort to services like Signal Private Messenger, a private chat app and messenger that runs in your browser.

This app says that it preserves your anonymity despite using your real phone number and your contact list. It comes along with the following features:

Send text messages, videos or images to individual contacts or to groups.

End-to-end encryption.

Message and conversation organization system.

Private calls by means of the VoIP protocol.

Private alternative to WhatsApp or Facebook Messenger

Regarding other apps that don't take privacy and encryption so seriously, this application is definitely a great alternative. How it works is very similar to other desktop messengers: we need to have the mobile app installed on our iPhone or Android to be able to use this version by means of a QR code.

Backed by security and privacy experts.

Open Whisper Systems is the company behind this development that's already available for Android and iPhone and that you can now also use on your desktop. People like Edward Snowden and other tech security experts like Matt Green, Bruce Schneier or Laura Poitras support the use of this tool on your PC.
